I was so hurt by my break up i realy understand what you are going through. I couldnt get him off my brain and for months i cried myself to sleep out because of it.. i kept figthing with myself pretending i didnt love him.. but i knew i did.. so in the end i gave up i accepted my feelings i allowed myself to love him and to send him love from a distance (we wernt in contact) after a while i got used to loving him from a distance at times i would get lonely and miss him but sending him love healed me. I learnt to love unconditionaly i loves this man even though we were not together and i know i always will. Emminating so much concentrated love for my ex eventualy brought him back into my life again.. he though about me the same as i thought about him even though it seemed he was completely careless.. but after a while a figured he was brought back into my life so i could love him and let him know he was loved, completely remove any negative emotions about him and move on with my life. It was part of my spiritual process.
But my messafe is to learn to love the person rather than trying to fogert about them or kidding yourself that you do not love the person. It will greatly benefit you.
